rust: drm: Return impl PinInit from drm::Registration::new()

Convert drm::Registration to return an impl PinInit<Self, Error> rather
than creating a separate allocation. This removes an otherwise
unnecessary allocation.

Update both in-tree callers (nova, tyr) to construct their bus device
private data using try_pin_init!().
